Why would having new litters born into the same environment that the parents existed in during QT be forbidden? That's got to be a mistake. I don't have any due now but if I did I guess I'd have to move them to a friends house...too weird.

There are diseased that can be perpetuated by breeding regularly...and that can be erradicated by not breeding for a couple months. There's a specific disease I'm thinking of...but I can't remember what it is...

You'd have to let me know what you're talking about before I believe that.

To imagine that a mother, would pass something to her litter (specifically, and not directly to other mice), then they'd pass that same thing on to other mice in the mousery, seems very unlikely to me.

You can have latent infections in adult animals (it happens in other species too....) that are not active and take a while to die off....but that can be passed to offspring in milk...babies have MUCH weaker immune systems than adults and these infections can become active again in them...and once they are active the germs can become stronger and cause new active infections in adults if they are introduced to it (either through the air, items being moved, or touching things/animals between cages).

I really wish I could remember the mouse disease I'm thinking of...but I don't even know how to search for it...lol

Regardless of what you believe may or may not be true...if one is having litters within the 4 weeks prior to RF, they are breaking the quarantine set by the organizers.

Pastuerellosis can lie dormant in a does, passed to her offspring through the birthing process, become "active" in them and then be spread via mucous or whatever to other parts of a colony just by not washing your hands.....
